合肥光伏發電安裝(zhuang)-合肥烈(lie)陽l價格便(bian)宜

光伏(fu)發電的主要(yao)原理(li)是半導體的光電效應。

光(guang)(guang)子(zi)(zi)(zi)照射到金(jin)屬(shu)(shu)上時，它的(de)能(neng)(neng)(neng)量可(ke)以被金(jin)屬(shu)(shu)中某個電(dian)(dian)(dian)子(zi)(zi)(zi)全部吸(xi)(xi)收，電(dian)(dian)(dian)子(zi)(zi)(zi)吸(xi)(xi)收的(de)能(neng)(neng)(neng)量足夠大，能(neng)(neng)(neng)克服金(jin)屬(shu)(shu)內部引力做功，離開金(jin)屬(shu)(shu)表面逃逸出來(lai)，成為(wei)光(guang)(guang)電(dian)(dian)(dian)子(zi)(zi)(zi)。硅(gui)原(yuan)(yuan)子(zi)(zi)(zi)有4個外(wai)(wai)層電(dian)(dian)(dian)子(zi)(zi)(zi)，如(ru)果在純硅(gui)中摻入有5個外(wai)(wai)層電(dian)(dian)(dian)子(zi)(zi)(zi)的(de)原(yuan)(yuan)子(zi)(zi)(zi)如(ru)磷原(yuan)(yuan)子(zi)(zi)(zi)，就成為(wei)N型(xing)半導體(ti)(ti);若在純硅(gui)中摻入有3個外(wai)(wai)層電(dian)(dian)(dian)子(zi)(zi)(zi)的(de)原(yuan)(yuan)子(zi)(zi)(zi)如(ru)硼原(yuan)(yuan)子(zi)(zi)(zi)，形成P型(xing)半導體(ti)(ti)。光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)是一種用(yong)太陽(yang)能(neng)(neng)(neng)來(lai)發(fa)(fa)電(dian)(dian)(dian)的(de)供電(dian)(dian)(dian)站(zhan)，它是利用(yong)太陽(yang)能(neng)(neng)(neng)電(dian)(dian)(dian)池方(fang)陣將太陽(yang)能(neng)(neng)(neng)輻射能(neng)(neng)(neng)轉換為(wei)電(dian)(dian)(dian)能(neng)(neng)(neng)的(de)光(guang)(guang)電(dian)(dian)(dian)技術(shu)來(lai)工(gong)作(zuo)的(de)。按照運行方(fang)式可(ke)分為(wei)并(bing)網型(xing)太陽(yang)能(neng)(neng)(neng)光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)站(zhan)和離網型(xing)太陽(yang)能(neng)(neng)(neng)光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)站(zhan)。太陽(yang)能(neng)(neng)(neng)作(zuo)為(wei)清潔可(ke)再生能(neng)(neng)(neng)源，對全社會有著廣泛而(er)特(te)別的(de)作(zuo)用(yong)。

當時國內的光(guang)伏行業發展并不完善，

在(zai)這個(ge)偏遠地(di)區(qu)建(jian)設(she)光(guang)(guang)伏電(dian)站是(shi)因為該地(di)區(qu)國家電(dian)網基礎設(she)施(shi)不(bu)完善，榆中地(di)區(qu)很多偏遠的(de)鄉村雖然(ran)用(yong)電(dian)量不(bu)大，但是(shi)還是(shi)沒有(you)通電(dian)，這個(ge)光(guang)(guang)伏電(dian)站為附近的(de)村莊(zhuang)帶去了(le)光(guang)(guang)明。晶體(ti)硅太陽能電(dian)池(chi)壽命可長(chang)達(da)20～35年。在(zai)光(guang)(guang)伏發電(dian)系(xi)統中，只要設(she)計合理(li)、選型(xing)適當，蓄(xu)電(dian)池(chi)的(de)壽命也可長(chang)達(da)10～15年。光(guang)(guang)伏發電(dian)公司歡迎(ying)您的(de)咨詢。
